Horizon Alert
Summary of the vulnerability and why it matters
A critical vulnerability exists in the login process of HPE Aruba Networking Private 5G Core On-Prem software. An attacker can trick a user into clicking a malicious link, which then redirects them to a fake login page designed to steal their credentials. This could potentially lead to unauthorized access and compromise of sensitive information.
- A fake login page can steal user credentials.
- Critical systems rely on secure login processes.
- Confirm if this software is used and assess exposure.
Attack Path
How an attacker could exploit the issue
An attacker can leverage a crafted URL to trick a user into visiting a malicious website. This website mimics the legitimate login page, prompting the user to enter their credentials. If the user falls for the deception, their credentials are stolen before they are redirected back to the genuine login page, making the attack harder to detect.
- Open redirect vulnerability in login flow.
- User clicks a crafted URL.
- Credential theft from authenticated users.
Live Threat
Current exploitation, exposure, and threat context
An attacker could exploit an open redirect in the login process of HPE Aruba Networking Private 5G Core On-Prem. When an authenticated user clicks a crafted URL, they might be sent to a fake login page on an attacker-controlled server. If the user enters their credentials on this spoofed page, the attacker could capture them before redirecting the user back to the legitimate login page.
- User credentials and session data.
- Via a crafted URL and user interaction.
- Credential theft and unauthorized access.
Operational Fix
Recommended remediation, mitigation, and detection steps
The HPE Aruba Networking Private 5G Core On-Prem's open redirect vulnerability in the login flow requires immediate attention from platform or infrastructure teams responsible for its operation. The first practical step is to locate all instances of this technology within your environment, assess their exposure and business criticality, identify the specific system owners, and then develop a remediation plan based on the assessed risk.
- Platform/infrastructure teams own remediation.
- Verify reachability and business criticality first.
- Plan coordinated remediation or risk reduction.
